The couple have a daughter, Penelope Charlevoix Gnoffo, who was born in March 2015.

"Heartburn, nausea and the emotional roller coaster were all worth it for this perfect soul," Terra continued.

"Life is going to be hectic with two babies under the age of 2, but there's nowhere else I'd want to be than in our little family."

Just one week before Grayson was born, Terra shared an Instagram of herself with a sweeping view of the ocean as her backdrop.

"Not knowing the surprise our family is blessed with is one of the most exciting parts of this pregnancy journey!" Terra wrote.

"As a child, I always wanted a sister to grow up with. My childhood was playing with GI Joes and learning all about basketball with my brother @bournodmark . Looking back, I cant imagine my life any different, nor would I wish for it to have ever changed.

"There is no doubt that Penelope will have an instant best friend no matter baby sister or brother.
